PRACTICE SAFE MAINTENANCE
To avoid accidents:
• Understand service procedures before starting work.
• Keep the work area clean and dry.
• Do not spray water or steam inside cab.
• Never lubricate or service the machine while it is moving.
• Keep hands, feet and clothing away from power-driven
parts.
Before servicing the machine:
1. Park the machine on a level surface.
2. Lower the bucket to the ground.
3. Turn the auto-idle switch off.
4. Run the engine at slow idle speed without load for 5 min-
utes.
5. Turn the key switch to OFF to stop engine.
6. Relieve the pressure in the hydraulic system by moving
the control levers several times.
7. Remove the key from the switch.
8. Attach a "Do Not Operate" tag on the control lever.
9. Pull the pilot control shut-off lever to the LOCK position.
10. Allow the engine to cool.
• If a maintenance procedure must be performed with the
engine running, do not leave machine unattended.
• If the machine must be raised, remove the attachment
and set the arm vertical against the ground. Securely sup-
port any machine elements that must be raised for ser-
vice work.
• Inspect certain parts periodically and repair or replace as
necessary. Refer to the section discussing that part in the
"MAINTENANCE" chapter of this manual.
• Keep all parts in good condition and properly installed.
• Fix damage immediately. Replace worn or broken parts.
Remove any buildup of grease, oil, or debris.
• When cleaning parts, always use nonflammable detergent
oil. Never use highly flammable oil such as fuel oil and
gasoline to clean parts or surfaces.
• Disconnect battery ground cable (−) before making ad-
justments to electrical systems or before performing
welding on the machine.
